iOS选项弹出窗口 - 类似于剪切/复制/粘贴 [英] iOS Option Popup - Similar to Cut/Copy/Paste

问题描述

对于我正在开发的应用程序，我需要一些弹出选项，类似于在UITextView或UIWebView中选择文本时显示剪切/复制/粘贴的方式。

For an app I'm developing I need some popup options, similar to how Cut/Copy/Paste is displayed when selecting text in a UITextView or UIWebView.

但是，我很难找到这种弹出窗口的名称。是否有公共API，或者它是否必须从头开始实现？

However, I'm having trouble finding what this kind of popup is called. Is there a public API for them, or is it something that has to be implemented from scratch?

推荐答案

你想要的课程看看是UIMenuController。

The class you want to look at is UIMenuController.

如果内存服务，则需要创建一个UIMenuItem实例数组来描述自定义操作，并使用'setMenuItems：'将它们添加到UIMenuController单例中。

If memory serves, you will need to create an array of UIMenuItem instances to describe the custom actions, and add them to the UIMenuController singleton using 'setMenuItems:'.
